【摘要】：中國的城市面臨著生態(tài)保護和經(jīng)濟發(fā)展的雙重壓力,如何有效協(xié)調(diào)城市發(fā)展和生態(tài)保護之間的矛盾,實現(xiàn)合理發(fā)展和合理保護,已成為學術(shù)界和決策部門面對的嚴峻挑戰(zhàn)。近年來,我國大部分城市經(jīng)歷了快速城鎮(zhèn)化進程和大規(guī)模的土地覆被利用變化,這給區(qū)域生態(tài)系統(tǒng)的結(jié)構(gòu)和功能帶來了嚴重的破壞,導致了水土資源短缺,水紋調(diào)節(jié)能力下降,生物棲息地和生物多樣性喪失,生態(tài)系統(tǒng)的審美、游憩服務質(zhì)量下降等問題。實踐證明:以人口預測為基礎(chǔ)的傳統(tǒng)城市規(guī)劃理論,和以建筑、交通基礎(chǔ)設(shè)施為主導的城市建設(shè)方式,是產(chǎn)生上述問題的主要根源之一,我國城市規(guī)劃體系急需一場根本性變革,以適應生態(tài)文明時代的新發(fā)展的和新要求。本研究基于生態(tài)安全格局構(gòu)建,來引導和限定城市擴張與城市形態(tài),從而實現(xiàn)對土地的精明保護與高效利用。生態(tài)安全格局構(gòu)建的關(guān)鍵在于城市的發(fā)展建設(shè)規(guī)劃必須以土地的生態(tài)過程和格局為依據(jù)和基礎(chǔ),優(yōu)先進行不建設(shè)區(qū)域的控制,再根據(jù)社會經(jīng)濟發(fā)展需要進行建設(shè)用地規(guī)劃和布局。這個不建設(shè)區(qū)域的核心就是生態(tài)基礎(chǔ)設(shè)施,是城市發(fā)展中不可逾越的生態(tài)底線。生態(tài)基礎(chǔ)設(shè)施由維護自然資產(chǎn)和生態(tài)系統(tǒng)服務的關(guān)鍵生態(tài)要素和格局構(gòu)成,是支撐人類社會可持續(xù)發(fā)展的基礎(chǔ)�；谏鷳B(tài)安全格局的城市空間布局規(guī)劃,在生態(tài)城市主義和生態(tài)學、景觀生態(tài)學之間,在自然資產(chǎn)、生態(tài)系統(tǒng)服務的概念和可持續(xù)發(fā)展之間架起了一座橋梁,是是實現(xiàn)精明保護與精明增長的有效途徑。它可為空間規(guī)劃提供重要的科學依據(jù),為主題功能區(qū)劃中的禁止建設(shè)區(qū)域和限制建設(shè)區(qū)域劃定提供重要參考。本文以榆林空港區(qū)為例,在生態(tài)安全格局構(gòu)建的指導下,綜合運用生態(tài)安全格局理論和GIS技術(shù),通過對凈空、采空區(qū)、生態(tài)斑塊過程的模擬和分析,判別維護上述過程安全的關(guān)鍵性空間格局,構(gòu)建綜合生態(tài)安全格局,并以生態(tài)安全格局為剛性框架,模擬榆林空港區(qū)空間拓展格局。因為空港的特殊性,空港城市的生態(tài)安全是極為脆弱的部分,嚴重影響了城市的可持續(xù)發(fā)展,從生態(tài)安全評價的角度出發(fā),進行空港城市的規(guī)劃是實現(xiàn)可持續(xù)發(fā)展的重要保障,近些年來,很少有學者以生態(tài)安全的角度去研究空港城市的規(guī)劃前景。生態(tài)安全評價,不僅是可持續(xù)發(fā)展于城市未來的保障,更加是可持續(xù)發(fā)展的現(xiàn)實意義的體現(xiàn),因此,在城市建設(shè)中去系統(tǒng)、科學的構(gòu)建空港城市的生態(tài)安全,就是從生態(tài)安全角度來體現(xiàn)規(guī)劃戰(zhàn)略的可持續(xù)性。根據(jù)城市規(guī)劃的復雜系統(tǒng)原理,同時運用系統(tǒng)科學的方法對榆林空港建設(shè)在不影響可持續(xù)發(fā)展的前提下,對自然生態(tài)系統(tǒng)的影響進行評價,發(fā)表對當前城市規(guī)劃的建議,這是預防榆林空港區(qū)生態(tài)系統(tǒng)向無序化發(fā)展和進行全局把控的重要手段之一。在綠洲保育、生態(tài)恢復、生態(tài)建設(shè)并重的前提下,以建設(shè)沙地生態(tài)產(chǎn)業(yè)體系、城市生態(tài)保護屏障的建設(shè),城市人居環(huán)境的改善、航空安全的保障為目標,建立生態(tài)良好的文明發(fā)展格局,開展城市生態(tài)環(huán)境治理和建設(shè),形成生產(chǎn)發(fā)展、生活富裕的整體文明格局。
[Abstract]:Chinese city facing the pressure of ecological protection and economic development, how to effectively coordinate the conflict between city development and ecological protection, rational development and reasonable protection, has become a serious challenge facing the academic and policy-making departments. Most of the city in recent years, China has experienced rapid urbanization and large-scale land cover by using change, which has brought serious damage to the structure and function of regional eco system, leads to the shortage of soil and water resources, decrease water regulation ability, habitat and biodiversity loss, ecological aesthetic, recreational service quality decline. The practice proves that the prediction of the traditional city planning theory based on population. And to the construction, transportation infrastructure is the dominant mode of city construction, is one of the main causes of the above problems, city planning system in China is urgently needed in a fundamental Change, to adapt to the new era of ecological civilization development and new requirements. This research is based on the construction of ecological security pattern, to guide and limit the expansion of the city and city form, so as to realize smart land conservation and utilization. The key is to construct the ecological security pattern of city development and construction planning based on ecological process and pattern of land as the basis and foundation, priority control construction area, according to the need of social and economic development of construction land planning and layout. The construction area is the core of ecological infrastructure, ecological city development is the bottom line. The impassable ecological infrastructure by key ecological factors to maintain the natural assets and ecosystem services and the pattern which is the foundation to support the sustainable development of human society. The city space layout planning based on the ecological security pattern, ecological urbanism and Ecology, landscape ecology, the natural assets, provides a bridge between sustainable development and the concept of ecosystem services, is the effective ways to achieve smart protection and smart growth. It can provide important scientific basis for spatial planning, provides an important reference for the theme of functional zoning in construction area and construction restrictions prohibited designated area. Taking Yulin airport area as an example, in the construction of ecological security pattern under the guidance of the integrated use of ecological security pattern theory and GIS technology, through the clearance, goaf, ecological patch process simulation and analysis of the spatial pattern of the identification of critical maintenance process safety, build a comprehensive ecological security pattern. And taking the ecological security pattern for the simulation of space rigid frame, Yulin airport zone development pattern. Because of the particularity of the airport, the airport city ecological security is extremely fragile, serious The influence of the sustainable development of the city, starting from the angle of ecological security evaluation, airport city planning is an important guarantee to realize the sustainable development in recent years, there are few scholars on the ecological security planning prospect perspective to study the airport city. Ecological security evaluation, sustainable development in the city is not only the future of security, more is reflected practical significance of sustainable development, therefore, to the system in city construction, ecological security construction of airport city of science, is to reflect the sustainable planning strategy from the perspective of ecological security. Based on the principle of complex system of city planning, and using the method of system science on the premise of Yulin airport construction without affecting the sustainable development under the and to evaluate the influence of natural ecological system, published in the current city planning proposal, which is to prevent the ecological system of Yulin airport area to disorder The development and the important means to control the global one. The ecological restoration in the oasis of conservation, ecological construction, and under the premise, in order to build sand ecological industry system, the construction of city ecological protection barrier, city living environment improvement, aviation security as the goal, to establish a good ecological development pattern, development of ecological city environmental management and construction, the formation of the development of production, affluent life civilization of the whole pattern.
